Hi all, new to the board and seeking advise. I'm looking to purchase a synth for home composition. I'm a piano player and as such weighted keys are important. I'd like an 88-key but not really sure what's out there. I'm most interested in a controller or master keyboard that I can add modules on later, so touch and key action are important to me. I would also like an on-board sequencer. I've been researching for days and can't seem to put my finger on anything.

I'm considering getting an older used model but was curious as to your recommendations. If I could find an older discontinued model to suit my needs and save some money at the same time that would be great.

Any thoughts?

TIA
